Chief Minister Of Gibraltar Fabian Picardo called it a 'dangerous incident'

It is unclear what the HMS Talent was doing in the Mediterranean but it sailed into Gibraltar on September 8.

Chief Minister Picardo added: “The matter must be taken up at the highest levels.

“We are showing our ability to cooperate on something as complex as the Brexit negotiations."

“We can surely get our act together in the more prosaic matter of our respective agencies navigating the crowded waters of the Bay.”

A Foreign Office spokesman told The Sun Online: "I can confirm that there was an incursion by a Spanish state vessel into British Gibraltar territorial waters this afternoon as a British submarine was leaving Gibraltar.

“This was challenged appropriately and will be protested to the Spanish Government.

“The Royal Navy challenges all unlawful maritime incursions into British Gibraltar territorial waters."
